Locke looked at this bottle of Beholder Elder Potion. The description on it read: [First Circle level potion. Based on the Beholder Lord Potion formula, it adds carapace materials from Abyss Crypt Lords, as well as other... materials, and its heat control becomes more complex...]

[Its effect is to increase the cultivation speed of meditation methods by increasing mental acuity. Through this method, it enhances the mental power of the user.]

[Warning: Has serious side effects. If the body has not established tolerance to Abyss energy, the moment it's consumed, one will suffer powerful Abyss energy erosion of the body, causing bodily collapse and transformation into an Abyss worm. It's recommended to start by taking Beholder Potion, then Beholder Lord Potion, and possess a powerful physical body to gradually establish good resistance to Abyss energy.]

Locke looked at this potion. He didn't plan to consume it for now, because this was the best example version for him to learn First Circle level potion studies and simultaneously create new First Circle potion formulas.

It would be too wasteful to consume it.

Using it, he could make rapid progress in the potion studies field.

First Circle level knowledge was rarely taught directly by teachers. Most of it was wizards reading books, literature, doing experiments, and researching on their own.

The knowledge transmission system artificially established during the wizard apprentice stage was only used by wizard society to lay foundations for wizard apprentices. In the First Circle wizard stage, everything depended on oneself.

There were no teachers, because everything could be one's teacher.

There were no specific textbooks, because everything around could become the source of one's knowledge.

And the First Circle potion studies knowledge Locke needed could also be exchanged from the library using contribution points.

Locke put away the Beholder Elder Potion and at the same time looked at the trembling 'ghostly hand', the Mammon demon, and began thinking about how to deal with this demon.

If it were an ordinary magical creature, he could directly imprison it in a restraint cage made by wizards of the Enchantment School. But this thing was a bizarre Abyss demon creature.

He didn't know if it could be contained inside.

The other party could even parasitize inside a first-grade wizard apprentice's soul for twenty years, continuously absorbing the other party's life force. He had to guard against this.

The Mammon demon sensed Locke's examining gaze and immediately became afraid. It remembered information about how cruel Abyss Lords would devour each other to evolve themselves.

"Don't eat me... great Beholder Lord... I can be a subordinate officer of your troops. No, no, no, no... I'm not worthy. I can be your vanguard army."

"You must be an Abyss Lord infiltrating the wizard world. You've already mixed into the upper echelons of human wizards. This subordinate is willing to become your vanguard army and help you trample the strongholds of human wizards."

The ghostly hand continuously promoted itself.

Locke's gaze remained cold as he considered how to deal with this thing. Keeping it seemed not bad.

First, it was a good source of information about the Abyss, which could further accelerate his improvement in Abyss potion studies.

Second, cutting off a bit of this thing could be used as raw material to refine Abyss potions. Moreover, he could restore its body by inputting life force into it, like a perpetual motion machine.

But how to preserve it was indeed a difficult problem.

Locke's eyes suddenly brightened. He snapped his fingers, and his first-grade wizard apprentice black wizard servant Howard immediately transformed into a vampire and instantly ran before Locke.

He had two black wizard servants. As for Niels, the black wizard who was previously taken on as a student by Witch Sophia, he became his assistant in Lilith's Cottage.

Black wizard Howard was captured by him as a prisoner and served as his experimental subject for a long time. Then he voluntarily submitted to him, and only then did he reluctantly accept him.

Therefore, Locke was more casual with Howard, unlike the other two black wizards whom he had to respect somewhat.

Locke said indifferently, "Open up your magical pressure structure. I'm going to put this thing inside your soul."

Howard was stunned for a moment but wasn't too afraid. Instead, his eyes even revealed joy. "Yes, Master. I will guard it well for you."

Locke glanced at him. "Aren't you going to ask me why?"

Howard knelt before Locke, his eyes extremely loyal. "Master, you are a great First Circle wizard. In black wizard lands, the opportunity to become a direct slave of a First Circle wizard is something others want but can't have."

"Moreover, you've recently been researching Abyss potion studies. This thing is an important experimental material. You definitely want to completely control it, so you absolutely won't let it lose control. Therefore, even if it's placed inside my soul, I have nothing to worry about."

"On the contrary, being able to make a greater contribution to Master is truly my honor."

Howard said while kneeling. 𝚏𝐫𝚎𝗲𝕨𝐞𝐛𝕟𝚘𝐯𝚎𝗹.𝕔𝐨𝗺

Locke looked at him with surprise. "You've been getting smarter lately."

Truly worthy of being a wizard cultivated by black wizard land values. His thought process was just different from normal people. However, what he said was also correct. This was actually relatively safe.

Locke's right hand manifested a Sea Gold Sand plant. Immediately, countless spore gold powder, under the action of the botanical spell model Scorching Gold Sand Flow, wrapped around this Mammon demon.

Because the Mammon demon mistakenly believed Locke was an Abyss Lord, it almost didn't resist.

Instead, it breathed a sigh of relief upon discovering that Locke only wanted to seal it.

The Mammon demon said with surprise, "Great Lord, you are an Abyss Lord. How can you master golden magic? Golden magic restrains us Abyss creatures..."

Locke wasn't surprised by this. Otherwise, he wouldn't have used Sea Gold Sand to seal this fellow.

One essence of Abyss energy was chaos, while the main characteristic of golden magic was immutable metallic nature. So of course golden magic would restrain Abyss creatures.

He had originally just wanted to try it. He hadn't expected it would actually succeed.

The golden cage formed by Scorching Gold Sand Flow restricted the Mammon demon. Locke placed it into Howard's shadow. The Mammon demon instinctively wanted to absorb Howard's life energy to restore its body.

Who knew that the next moment, the Mammon demon felt nauseous. "Ugh... Lord, sir, what is this thing? Why is his life energy so disgusting? Is he really a life form of the prime material plane? Lord, sir, among all plane life forms, the life energy of wizard world life is the most delicious. But why does his life energy taste so much like expired moldy food?"

That's right. Howard's zombie body was Locke's second restriction on this demon.

Of course it tasted like expired moldy food. The vampire's immortality was just exploiting a bug between life and death, existing outside death and life.

Locke indicated to Howard indifferently, "You performed very well this time. I'll give you a bottle of Minor Viridian Potion to drink every day to help you improve your resistance to Abyss energy."

"You can rest assured about this."

Howard simply felt that Locke was the most conscientious slave master in the world. He said emotionally, "Thank you, Master."

Locke instructed him, "Send Yuri back. After she wakes up, tell her she's completely healed."

"Let her make good use of this hard-won second life."

Howard looked at Yuri lying unconscious on the operating table. At this moment, without the ghostly hand possessing her, Yuri's body was actually beginning to restore some of her youth.

After a period of time, she would fully restore to the appearance appropriate for her age.

Howard said, "Yes, Master. Master, you're being too merciful to her."
